Facile synthesis of CuMn2O4 nanoparticle supported on MoS2 nanorods via hydrothermal route for supercapacitor application

In the field of material sciences, synergistic effects manifest that the collective qualities of a composite material surpass the physical and chemical capabilities of its constituent components. The present study deals with the production of MoS2 (MS), CuMn2O4 (CMO) and MoS2/CuMn2O4 (MS/CMO) nanocomposites using a hydrothermal approach. The study examined the influence of MoS2 incorporation on electrochemical features of the nanohybrids. The notable enhancement in the electrochemical behaviour of the nanohybrid may be related to the synergistic interaction between the CMO and MS. The observed enhancement in electrochemical characteristics in the MS/CMO nanocomposite might be related to its increased specific interfacial area and small crystallite size. In conventional three-electrode configuration using 2.0 M KOH, MS/CMO nanohybrid exhibits notable specific capacitances of 1244 F g(-1) at 1.0 A g(-1). The noteworthy aspects of improved electrochemical phenomenon include high-rate capabilities and superior cyclability. The experimental findings demonstrate that a symmetric supercapacitor system, including an MS/CMO nanocomposite, has specific energy of 25 Wh kg(-1) and a retention capacitance of 93 %. The production technique, which is characterized by its simplicity and positive electrochemical outcomes, provides support to our hypothesis that the proposed MS/CMO nanohybrid has the capacity for utilization in the advancement of efficient and effective supercapacitor devices.
